I woke up in my sleep, and a strange door appeared in my home…Behind every door is a strange world.

In the nightmare world, Jiang Cheng added the news from the strong man to the fat man, and he almost cried when he heard the latter, “If you die here, the whole family will stand upside down and bleed?”

“Is such that.”

“Then I don’t think you are too scared?” The fat man widened his eyes.

Jiang Cheng turned his head and said in a very formal tone: “Because I am an orphan.”

The technology fanatic Huo Tian from the future world died because of a research accident and transmigrated into the body of a fake rich daughter from a wealthy family.

Before the real daughter of the family came back, she was the treasure of the family, and everyone treated her like a princess. After the real daughter returned, her status plummeted, and they treated her as an outsider.

Living in a wealthy family that valued blood relations the most, Huo Tian, an unrelated outsider, was given a hard time. Everyone hated and despised her. Leaving behind a letter of severance, Huo Tian left the Huo Family on her own accord without any lingering reluctance for her once luxurious life.

She started a new life with the original Huo Tian’s biological mother and uncle, who had been abandoned by the Huo Family’s real rich daughter. She started a business from scratch.

With her understanding of the future world and her grasp of futuristic technology, Huo Tian quickly became famous in the business circle and established a research company that was renowned throughout the country. All the researches from her company were ten years more advanced than everywhere else in the world. With every research published, the whole world would be taken aback and impressed by how miraculous it was.

As time passed, Huo Tian became increasingly successful. Just as she was getting used to being called a fake rich daughter, the secret that her biological mother hid was out of the bag—Huo Tian’s biological father was the head of the noblest and the most powerful wealthy family at an international level, the Xi Family.

Compared to the Xi Family, the Huo Family was nothing but insignificant. The fake rich daughter in everyone’s eyes and the joke among the wealthy circle suddenly became a real rich daughter of the most influential family. Moreover, the head of the Xi Family seemed to be spoiling his long-lost daughter to the heavens...

Fear breaks the boundaries between dreams and reality, and it is impossible to tell which is reality and which is illusory. When the nightmare really comes, no one can be alone.

This is both a danger and an opportunity.
